Marci A. Hamilton, a professor at the University of Pennsylvania, criticizes the Trump administration’s failure to adequately handle the national coordination of efforts to get the COVID-19 crisis under control. Hamilton points out that the Framers of the Constitution anticipated that the country would face emergencies and intentionally consolidated power in a single President to make decisions to unify and protect the nation.

Cornell law professor Michael C. Dorf implores the President or Congress to act swiftly and drastically to address the COVID-19 pandemic: lock down the nation and suspend habeas corpus. Dorf explains why this extreme measure is both appropriate and necessary in a situation such as this one.

Illinois Law dean and professor Vikram David Amar explains why a local government cannot constitutionally create policy discriminating against entities that do business with the feds. Specifically, Amar discusses a situation in which the city of Farland, California, is trying to prevent a privately operated state prison facility located in that city from contracting with Immigration and Customs Enforcement (ICE).

Illinois Law dean and professor Vikram David Amar comments on a recent decision by the U.S. Court of Appeals for the Second Circuit regarding so-called “sanctuary” jurisdictions. Amar argues that while the Second Circuit may have arrived at the correct conclusion of law, it also misunderstood the Supreme Court’s decision in NFIB v. Sebelius, in which the Court struck down the “Medicare expansion” provision of the Affordable Care Act as unconstitutionally coercive. Amar points out that in Sebelius, the Court found the fact that the Medicare expansion provision of the ACA vitiated the terms of a preexisting deal was sufficient to hold that provision coercive.

Cornell law professor Michael C. Dorf comments on a lawsuit in which New York State and other plaintiffs are suing the federal government over an immigration policy of arresting undocumented immigrants when they appear in state court on unrelated matters. Dorf explains why the federal judge hearing the case should reject the government’s motion to dismiss the lawsuit.

Illinois law dean and professor Vikram David Amar comments on the Trump administration’s recent legal challenge to California’s law that denies ballot access to presidential candidates who have chosen not to release their tax returns. Without opining as to whether that challenge is likely to succeed or whether it is a good idea for states to enact such laws, Amar explains why, as a normative matter, the arguments in favor of striking down the law are misplaced, or at the very least, overly simplistic.

Illinois law dean and professor Vikram David Amar contrasts Florida’s recent enactment of one of the strictest measures in the country to prohibit state and local entities from becoming “sanctuary” jurisdictions with California’s pro-sanctuary state laws. Amar explains this autonomy of states to enact such different laws with respect to federal laws as a product of the so-called anti-commandeering doctrine the Supreme Court has applied in three major cases over the past quarter century.

Illinois law dean and professor Vikram David Amar considers whether the federal government can subject so-called sanctuary jurisdictions to liability for crimes committed by private persons who are in the United States unlawfully, as two Republican-backed legislative proposals seek to do. Specifically, Amar discusses whether such liability constitutes unconstitutional commandeering of states under existing Supreme Court precedent.

Illinois Law dean and professor Vikram David Amar explains why the US Supreme Court was right to leave undisturbed the recent congressional redistricting ruling by the Pennsylvania Supreme Court. Amar describes the important role (and limitations) of state courts and state legislative bodies in our federal system.

Cornell University law professor Michael C. Dorf comments on the recent announcement by Attorney General Sessions that the Trump Department of Justice was rescinding an Obama administration policy toward state-legal marijuana. Dorf argues that the policy shift breaks promises by then-candidate Trump and then-Senator Sessions, but that objections to the new policy on federalism grounds are largely misguided.

Cornell University law professor Michael C. Dorf considers whether the new tax law, which disproportionally affects “blue” states as compared to “red” states due to changes to the deductions for state and local taxes (SALT), is unconstitutional. Dorf explains some of the possible arguments against the law but ultimately concludes that due to difficulties of proof, courts probably won’t end up ruling that the SALT deductibility cap violates the First Amendment or a core principle of federalism.

Illinois Law dean and professor Vikram David Amar explains the federalism doctrines implicated by Attorney General Sessions’ attempt to deny funding to sanctuary jurisdictions. Amar points to lower court decisions that reflect a misunderstanding of the doctrines and calls upon federal courts and their law clerks to better understand and apply not just the nuanced technical details of various specific doctrines, but the overall federalism big picture as well.

Illinois Law dean and professor Vikram David Amar comments on recent actions by state and local governments to oppose federal policies, such as the immigration and the wall along the U.S.–Mexico border. Amar argues that these attempts likely run contrary to the Supremacy Clause of the U.S. Constitution by attempting to interfere with the execution of federal policy.

Illinois Law dean and professor Vikram David Amar discusses several legislative proposals in various states that purport to give state legislatures power to interpret and implement the federal Constitution notwithstanding judicial rulings interpreting the same. Amar explains some of the key differences between the different proposals and why some are likely to pass constitutional muster while others are not.

Cornell University law professor Michael Dorf argues that in some contexts, consideration of states’ rights is relevant to the interpretation of federal statutes, but in other contexts—including the federal lawsuit over a transgender boy’s access to a boys’ restroom at school—principles of federalism are outweighed by other considerations. Dorf provides three examples of instances where federalism should play a role in the interpretation of federal statutes, and he explains why the transgender bathroom case differs from those instances.
